It looks as if Rick Santorum is going to lose Wisconsin on Tuesday. That said, if Santorum fails to capture a win in Pennsylvania (April 24) - his home state, then we can have a legitimate discussion on whether the former Pennsylvania senator should bow out of the race. CNN's Gabriella Schwarz reports:
Rick Santorum sounded like the ever confident Republican presidential candidate when asked about his chances in Pennsylvania's April primary.
The former two-term Pennsylvania senator on Monday said he could "absolutely" guarantee a win in the state, but that it's a "tough state."
Despite his uphill delegate climb and falling poll numbers in the 2012 campaign, Santorum has vowed to remain in the race until a candidate reaches 1,144 delegates, the necessary number to clinch the GOP presidential nomination.
